What is vitamin B3 (niacin)?

Vitamin B3 or niacin is a water-soluble B-complex vitamin. It is naturally found in foods such as chicken, tuna, peanuts, and legumes. However, sometimes the diet does not provide enough, and a supplement can help reach adequate levels. Niacin participates in over 200 enzymatic reactions, especially in energy production from food. There are two main forms: nicotinic acid (present in this product) and nicotinamide (niacinamide). Both are effective, but they have important differences.

Benefits backed by EFSA

The European Food Safety Authority (EFSA) has approved several health claims for niacin. According to EFSA:

• Niacin contributes to normal energy-yielding metabolism.
• Niacin contributes to the normal functioning of the nervous system.
• Niacin contributes to normal psychological function.
• Niacin contributes to the maintenance of normal skin and mucous membranes.
• Niacin contributes to the reduction of tiredness and fatigue.

Forms of niacin: niacin vs niacinamide

This supplement contains niacin in the form of nicotinic acid. A notable characteristic of this form is that it can cause a flushing or warming sensation in the skin, known as "niacin flush". This effect is harmless and usually subsides after a few minutes. In contrast, niacinamide (another form of vitamin B3) does not produce this effect. Why choose niacin then? Because some studies suggest that nicotinic acid could have additional benefits on the lipid profile, although there are no EFSA approved claims for this use. If you prefer to avoid the flush, you can opt for niacinamide, but this product is designed for those seeking the active form of niacin.

Recommended dosage

The recommended daily dose of niacin varies according to age, sex, and individual circumstances. For adults, the reference intake is usually between 14 and 16 mg per day. This product provides 100 mg per tablet, a higher dose than recommended, so it is considered a high-potency supplement. The dose of one tablet per day should not be exceeded without consulting a healthcare professional. The tolerable upper limit for niacin (nicotinic acid) is 35 mg/day according to EFSA, although higher doses can be used under medical supervision. It is always advisable to start with a low dose and gradually increase it to minimize the flush.

How to take niacin

To minimize the possible flushing effect, it is recommended to take the tablet during meals, preferably with foods containing some fat. Avoid consuming alcohol with niacin, as it can intensify the flush. It is also useful to start with a lower dose (for example, by splitting the tablet) and gradually increase it over several weeks. Maintain adequate hydration and do not exceed the indicated dose.

Storage and conservation

Store the tablets in a cool, dry place, protected from direct light and out of reach of children. Do not use the product if the seal is damaged or has passed the expiration date. Proper storage ensures the effectiveness of the supplement until the end of its shelf life.

Possible side effects

The most common side effect of niacin is flushing, which may be accompanied by itching or a sensation of warmth. This is normal and usually disappears with continued use. To reduce it, it is recommended to take the tablet with food or avoid alcohol consumption with niacin. At very high doses (above 500 mg/day), gastrointestinal discomfort or elevation of liver enzymes may occur. If you experience any persistent symptoms, consult your doctor. This product should not be used as a substitute for a balanced diet and it is important to maintain a varied diet.

Who can benefit from niacin supplementation?

People with restrictive diets, vegetarians or vegans who do not consume enough niacin-rich foods, those with chronic fatigue, or who seek to support their energy metabolism may find this supplement useful. It may also be beneficial for those with skin problems such as dermatitis, always under professional advice. Remember that supplements are a complement, not a treatment, and it is best to consult a dietitian or doctor before starting any supplementation.
